JAMES THOMAS HAM, OF MONAHANS, TEXAS.

WINDMILL.

SPECIFICATION forming part of Letters Patent No.'738,675, dated September 8, 1903.

Application filed February 18, 1903. Serial No. 143,914. (No model.)

To all whom it may concern:

Be it known that I, JAMES THOMAS HAM, a citizen of the United States, residing at Monahans, in the county of Ward and State of Texas, have invented new and useful Improvements in Windmills, of which the fol lowing is a specification.

My invention relates to new anduseful improvements in windmills and its object is to provide a device of this character having a .wheelof novel construction whereby the wind coming into contact therewith is concentrated and the full force thereof applied to the wheel. A further object is to employ means whereby motion is imparted from the wheel to apparatus located adjacent thereto.

Another object is to provide abalance for the mechanism whereby the power necessary I to operate it is reduced to the minimum.

With the above and other objects in view the invention consists in the novel construction through the wind-wheel.

Referring to the figures by numerals of reference, 1 is a supporting-frame'of suitable height, and a preferably rectangular head 2 is arranged therein and bears upon a crossbeam '3, as shown. A stem at extends upward from the center of the head 2 and bears within the top of frame 1, and hinged to this stem are a tail-vane 5 and a side vane 6. An arm 7 projects from stem 4 in alinement with the side vane and is connected by a rod 8 with the arm 9 of tail-vane 5. A spring 10 serves to hold the vane 5 normally in proper relation to the wheel. This wheel comprises a cylindrical casing 11, suppo'rted upon a shaft 12 by arms 13. This shaft is journaled in the sides of the head 2 and has a crank 1-1 at each end thereof. Curved blades 15 are interposed between the shaft 12 and casing 11.

A cross-head 16 is slidably mounted in slots 17, formed in the sides of head 2, and the ends of the cross-head are connected to the cranks 1 1 by pitmen 18. To the center of rod at the bottom, and at each end thereof is arranged a toothed wheel 22, and these extend to opposite sides of the blade 20. Inclined stationary cutting-blades 23 are mounted on the bottom of frame 1, and a lever 21 is fulcrumed thereto and has its two edges sharpened to form a knife 25. One end of the lever is connected to the rod 19 by a link,

while the other end has an adjustable weight.

26 thereon.

Wind upon coming into contact with the blades 15 is prevented from flowing laterally therefrom by the cylindrical casing 11. This casing holds or concentrates the wind,and the full force thereof is therefore imparted to the wheel. As the wheel revolves a reciprocating movement is imparted to rod 19 by the cranks 14- and pitmen 1S, and saw-blade 20 and lever 24 are moved therewith. By placing a log on the wheels 22 the weight thereof will cause them to revolve, and it will be fed to the saw. The weight 26 can be adjusted upon lever 24, so as to act as a counterbalance, and straw or other similar material can be placed between either blade 23 and the knife 25 and will be the right to make such changes as fairly fallwithin the scope of my invention.

Having thus described the invention, what is claimed as new is-- 1. In a windmill, the combination with a frame, a rotary head mounted therein, and a wheel journaled in the head 5 of a cross-head V slidably mounted in the head, means for imparting motion thereto from the Wheel, a pump-rod connected to the cross-head, a cutting-lever f ulcrumed in the frame, a link connection between the lever and rod, and an adjustable Weight upon the lever.

2. The combination with a frame, a rotary head therein, a crank-shaft in the head and a Wheel secured to the shaft; of a cross-head slidablyrmounted in said head, a pitman connecting said cross-head and the crank-shaft, a pump-rod secured to the cross-head, cutting-blades, a cutting-lever fulcrumed therebetWeen, a link connecting the lever and rod, and an adjustable Weight upon the lever.

3. The combination with a frame, a rotary head therein, a crank-shaft in the head and a Wind-wheel secured to the shaft; of acrosshead slidably mounted in the head, a pitman connecting said cross-head and the crankshaft, a pump -rod connected to the crosshead, a saw-blade secured to and projecting from said rod, a lever connected to the rod, and an adjustable Weight upon the lever.

4. The combination vvith a wind-wheel, a rod, and means for transmitting motion from the wheel to the rod; vof a cutting-lever conneoted to and operated by the lever, an adjustable Weight upon said lever, a knife adjacent to the lever, and a saw-blade upon the rod.

5. In a Windmill, the combination With a frame; of a head revolubly mounted therein, vanes hinged to the head, a crank-shaft journaled in the head, a wheel thereon, a crosshead slidably mounted in the head, a pitman connecting the shaft and cross-head, a rod extending from the cross-head, a saw-blade thereon, a cutting-lever connected to the rod, and an adjustable counterbalance -weight upon the lever.

In testimony whereof I affiX my signature in presence of two Witnesses.
